Apocrine metaplasia, specifically, involves the development of cells resembling those in apocrine glands, characterized by their distinctive cytoplasmic features. Apocrine metaplasia in the gallbladder represents a new and intriguing discovery, marking a significant milestone in medical literature. Furthermore, clear cell metaplasia is often observed in other organs like the cervix and has never been documented in the gallbladder. The coexistence of apocrine and clear metaplasia challenges existing paradigms surrounding gallbladder pathology, prompting a reevaluation of the underlying mechanisms that drive these cellular transformations.

This case report discusses the incidental discovery of a cervical rib in a 53-year-old woman presenting with acute cholecystitis. While cervical ribs are rare, their identification holds clinical significance due to their potential implications for vascular compression or thoracic outlet syndrome. Despite the patient's primary complaint of cholecystitis, a chest X-ray incidentally revealed the cervical rib. This finding underscores the importance of a thorough radiographic examination. The report discusses similar cases, emphasizing varying clinical presentations and associated vascular complications. The case highlights the necessity for a comprehensive assessment of incidental findings to ensure holistic patient care and management, emphasizing the importance of considering anatomical variants in clinical practice.

PURPOSE
To formulate and evaluate the diagnostic performance and utility of a new CT difficulty score in predicting difficult laparoscopic surgery in cases of gallbladder (GB) perforation.
METHODS
This prospective single centre study included a total of 48 diagnosed cases of GB perforation on CT between December 2021 and June 2023, out of which 24 patients were operated. A new 6-point CT difficulty scoring system was devised to predict difficult laparoscopic approach, based on patterns of inflammation around the perforated GB that were found to be surgically relevant. The pre-operative imaging findings on CT were studied in detail and correlation coefficients of various imaging findings were calculated to predict difficult surgery.
RESULTS
On CECT, the type of perforation, according to the revised Niemeier's classification could be exactly delineated in all 48 patients. A CT difficulty score of ≥ 3 was found to a good predictor difficult laparoscopic approach, with statistical significance (p = 0.001), sensitivity of 94.44%, specificity of 83.33%, PPV of 94.44% and NPV of 83.33%. Inflammatory changes around duodenum showed maximum correlation coefficient of 0.744 (p = 0.0001), around colon showed a correlation coefficient of 0.657 (p = 0.0005), and in the omentum had a correlation coefficient of 0.5 (p = 0.013)). Inter-observer agreement was also calculated for various findings and it was found to have moderate to strong agreement (κ value 0.5-1.0).
CONCLUSION
The CT difficulty scoring system can be an effective tool in predicting difficult laparoscopic surgery in cases of GB perforation in an emergency setting which can help in decision making and improved patient outcome.

BACKGROUND
The aim of this study was to establish features of inflammation in histologically normal gallbladders with gallstones and compare the expression of inflammatory markers in acutely and chronically inflamed gallbladders.
METHODS
Immunohistochemistry was performed on formalin-fixed paraffin-embedded gallbladders for tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-2R, and substance p in three groups: Group I (n = 60) chronic cholecystitis, Group II (n = 57) acute cholecystitis and Group III (n = 45) histologically normal gallbladders with gallstones. Expression was quantified using the H-scoring system.
RESULTS
Median, interquartile range expression of mucosal IL-2R in Groups I (2.65, 0.87-7.97) and II (12.30, 6.15-25.55) was significantly increased compared with group III (0.40, 0.10-1.35, p < 0.05). Submucosal IL-2R expression in Groups I (2.0, 1.12-4.95) and II (10.0, 5.95-14.30) was also significantly increased compared with Group III (0.50, 0.15-1.05, p < 0.05). There was no difference in the lymphoid cell IL-6 expression between Groups I (5.95, 1.60-18.15), II (6.10, 1.1-36.15) and III (8.30, 2.60-26.35, p > 0.05). Epithelial IL-6 expression of Group III (8.3, 2.6-26.3) was significantly increased compared with group I (0.5, 0-10.2, p < 0.05) as was epithelial TNF-α expression in Group III (85.0, 70.50-92.0) compared with Groups I (72.50, 45.25.0-85.50, p < 0.05) and II (61.0, 30.0-92.0, p < 0.05). Lymphoid cell Substance P expression in Groups I (1.90, 1.32-2.65) and II (5.62, 2.50-20.8) was significantly increased compared with Group III (1.0,1.0-1.30, p < 0.05). Epithelial cell expression of Substance P in Group III (121.7, 94.6-167.8) was significantly increased compared with Groups I (75.7, 50.6-105.3, p < 0.05) and II (78.9, 43.5-118.5, p < 0.05).
CONCLUSION
Histologically normal gallbladders with gallstones exhibited features of inflammation on immunohistochemistry.

A comparison of outcomes including bile duct injury of subtotal cholecystectomy versus open total cholecystectomy as bailout procedures for severe cholecystitis: A multicenter real-world study.
BACKGROUND
Dense inflammation obscuring the hepatocystic anatomy can hinder the ability to perform a safe standard laparoscopic cholecystectomy in severe cholecystitis, requiring use of a bailout procedure. We compared clinical outcomes of laparoscopic and open subtotal cholecystectomy against the traditional standard of open total cholecystectomy to identify the optimal bailout strategy for the difficult gallbladder.
METHODS
A multicenter, multinational retrospective cohort study of patients who underwent bailout procedures for severe cholecystitis. Procedures were compared using one-way analysis of variance/Kruskal-Wallis tests and χ tests with multiple pairwise comparisons, maintaining a family-wise error rate at 0.05. Multiple multivariate linear/logistical regression models were created.
RESULTS
In 11 centers, 727 bailout procedures were conducted: 317 laparoscopic subtotal cholecystectomies, 172 open subtotal cholecystectomies, and 238 open cholecystectomies. Baseline characteristics were similar among subgroups. Bile leak was common in laparoscopic and open fenestrating subtotal cholecystectomies, with increased intraoperative drain placements and postoperative endoscopic retrograde cholangiopancreatography(P < .05). In contrast, intraoperative bleeding (odds ratio = 3.71 [1.9, 7.22]), surgical site infection (odds ratio = 2.41 [1.09, 5.3]), intensive care unit admission (odds ratio = 2.65 [1.51, 4.63]), and length of stay (Δ = 2 days, P < .001) were higher in open procedures. Reoperation rates were higher for open reconstituting subtotal cholecystectomies (odds ratio = 3.43 [1.03, 11.44]) than other subtypes. The overall rate of bile duct injury was 1.1% and was not statistically different between groups. Laparoscopic subtotal cholecystectomy had a bile duct injury rate of 0.63%.
CONCLUSION
Laparoscopic subtotal cholecystectomy is a feasible surgical bailout procedure in cases of severe cholecystitis where standard laparoscopic cholecystectomy may carry undue risk of bile duct injury. Open cholecystectomy remains a reasonable option.

INTRODUCTION
Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have attracted much attention because of their significant hypoglycemic and weight-loss effects. Previous preparations can only be subcutaneously injected. Oral administration of GLP-1RAs semaglutide helps to broaden treatment options, but its safety in the real world still needs to be observed. This study is based on FDA adverse event reporting system (FAERS) database to mine adverse drug events (ADE) of oral semaglutide, and provide references for the clinical safe use of this drug.
METHODS
To analyze the signal quality of oral semaglutide, which is a drug used in the FAERS database from the third quarter of 2019 to the third quarter of 2023, we collected ADE data and performed data mining by using disproportionate analysis. Then, we standardized the data and used a variety of signal-quantification techniques, including reported odds ratio (ROR), proportional reporting ratio (PRR), Bayesian belief propagation neural network (BCPNN), and multiple empirical Bayesian gamma Poisson contractions (MGPS), for further analysis.
RESULTS
We screened 2398 reports on the use of semaglutide tablets, involving a total of 5653 ADE. These reports were mainly submitted by consumers, and the reporting country was mainly the United States. A total of 23 system organ classes (SOC) and 93 preferred terms (PT) were mined for the signals of semaglutide tablets. The three most common SOC were gastrointestinal disorders, general disorders and administration site conditions, and investigations. At the PT level, metabolism and nutrition disorders exhibit the highest number of signals, with the top three being thyroid cyst, acute cholecystitis, and ketosis. Gastrointestinal disorders rank second, primarily involving eructation, pancreatitis, impaired gastric emptying, and regurgitation. In addition, vith nerve paralysis occurs and the signal intensity is high.
CONCLUSIONS
Our study provides a deeper and broader understanding of the safety of oral semaglutide. The results of the ROR, PRR, BCPNN, and MGPS algorithms exhibit high consistency, with metabolism and nutrition-related disorders having the highest number of signals. The conclusions align with the technical specifications of the product. Notably, other unexpected effects are reported, including acute cholecystitis, paralysis of the abducens nerve, and positional vertigo.

OBJECTIVE
The aim of this prospective, single-center cohort study was to analyze serum leucine-rich α-2-glycoprotein-1 (LRG1) expression in patients with acute cholecystitis (AC) and to investigate its variation depending on symptom duration.
PATIENTS AND METHODS
Participants were divided into patients with AC and a healthy control group. At the time of diagnosis, blood samples were collected, and symptom onset times were questioned. Collected serum LRG1 levels were measured.
RESULTS
30 patients and 30 healthy volunteers were included in the study. LRG1 (p=0.008), white blood cells (WBC) (p<0.001), platelet (p=0.003), neutrophil (p<0.001), lymphocyte (p=0.001), and CRP (p=0.014) were significantly different in AC patients vs. the control group. When the correlations of serum laboratory values with the time of onset of symptoms were compared, LRG1 (p<0.001) was significantly correlated, while no significant correlation was observed in C-reactive protein (CRP) (p=0.572), WBC (p=0.155), and neutrophil (p=0.155).
CONCLUSIONS
LRG1 expression increases after 24 hours in AC patients. Due to its correlation with symptom duration, we believe it can be helpful for timing cholecystectomy.

BACKGROUND
Autoimmune pancreatitis (AIP) is a rare form of autoimmune-mediated pancreatitis, which is easily misdiagnosed as pancreatic cancer and thus treated surgically. We studied the diagnosis and treatment of a patient with type 1 AIP recently admitted to our hospital, and reviewed the literature to provide a reference for clinical diagnosis of AIP.
CASE SUMMARY
The chief complaint was yellowing of the body, eyes and urine for 21 d. The patient's clinical presentation was obstructive jaundice and imaging suggested pancreatic swelling. It was difficult to distinguish between inflammation and tumor. Serum immunoglobulin G4 (IgG4) was markedly elevated. IgG4 is an important serological marker for type 1 AIP. The patient was diagnosed with AIP, IgG4-related cholangitis, acute cholecystitis and hepatic impairment. After applying hormonal therapy, the patient's symptoms improved significantly. At the same time, imaging suggested that pancreatic swelling subsided, and liver function and other biochemical indicators decreased. The treatment was effective.
CONCLUSION
In patients with pancreatic swelling, the possibility of AIP should be considered.

Introduction Gallstone ileus is an uncommon cause of small bowel obstruction; it is a rare complication of calculus chronic cholecystitis which leads to cholecystoenteric fistula and impaction of gallstone in the gastrointestinal tract leading to mechanical bowel obstruction. Our aim is to report the natural history and management of this rare condition in a teaching hospital. Materials and methods It is a retrospective study, where 10 years of data related to the management of intestinal obstruction secondary to gallstone ileus was collected. The cohort included 10 patients, whose demographic data, clinical findings, and management outcomes were evaluated. Results Majority of patients were female (90%, n=9) with a median of 83 years (range 61-96) although 90% of the population were above 70 years. Presenting complaints were mostly pain and vomiting. The onset of symptoms was between two and seven days. The site of obstruction was mostly the ileum (n=9) with the exception of one case in the sigmoid proximal to a benign stricture, and the size of the stone ranged from 2.5 to 4 cm. Moreover, most of the patients had a previous history of gallstone (n=7) with one post-cholecystectomy status. The laboratory investigations in 50% of patients had deranged liver function test (LFT) and acute kidney injury (AKI), and 60% had raised inflammatory markers, namely, white blood cells (WBC) and C-reactive protein (CRP). Intervention as enterolithotomy was the preferred approach (n=8 (two laparoscopic, six open surgery)), and two patients were managed conservatively. The mean postoperative length of stay was 10 days in the open approach and five days in the laparoscopic approach, respectively. Conclusions Elderly female patients are more prone to have gallstone ileus particularly with a past medical history of gallstones, and the preferred management option is enterolithotomy which could be open or laparoscopic depending on the expertise of the surgeon.

OBJECTIVES
Some patients undergo both computed tomography (CT) and ultrasound (US) sequentially as part of the same evaluation for acute cholecystitis (AC). Our goal was to perform a systematic review and meta-analysis comparing the diagnostic performance of US and CT in the diagnosis of AC.
MATERIALS AND METHODS
Databases were searched for relevant published studies through November 2023. The primary objective was to compare the head-to-head performance of US and CT using surgical intervention or clinical follow-up as the reference standard. For the secondary analysis, all individual US and CT studies were analyzed. The pooled sensitivities, specificities, and areas under the curve (AUCs) were determined along with 95% confidence intervals (CIs). The prevalence of imaging findings was also evaluated.
RESULTS
Sixty-four studies met the inclusion criteria. In the primary analysis of head-to-head studies (n = 5), CT had a pooled sensitivity of 83.9% (95% CI, 78.4-88.2%) versus 79.0% (95% CI, 68.8-86.6%) of US (p = 0.44). The pooled specificity of CT was 94% (95% CI, 82.0-98.0%) versus 93.6% (95% CI, 79.4-98.2%) of US (p = 0.85). The concordance of positive or negative test between both modalities was 82.3% (95% CI, 72.1-89.4%). US and CT led to a positive change in management in only 4 to 8% of cases, respectively, when ordered sequentially after the other test.
CONCLUSION
The diagnostic performance of CT is comparable to US for the diagnosis of acute cholecystitis, with a high rate of concordance between the two modalities.
CLINICAL RELEVANCE STATEMENT
A subsequent US after a positive or negative CT for suspected acute cholecystitis may be unnecessary in most cases.
KEY POINTS
When there is clinical suspicion of acute cholecystitis, patients will often undergo both CT and US. CT has similar sensitivity and specificity compared to US for the diagnosis of acute cholecystitis. The concordance rate between CT and US for the diagnosis of acute cholecystitis is 82.3%.
